Also could research the many rca to wireless/bluetooth transmit/receivers for surrounds, wides, height etc. Get a nice pair of speakers that sound good to you for 2ch stereo listening. They will then be fine for fronts for the HT. Look at an onkyo or denon for the receiver. Good midfi and not break the bank. I did all klipsch 11.1 for HT I’ve had for years that was, all in, probably more than $3k, but not by much.
I built an entirely separate system for stereo though.
